JOHN I. ROLLOYV, OF FREDERICKSBURG, "IRGINIA, ASSIGNOR TO CHARLES C. VELLFORD, OF SAME PLACE.

THRESHING-MACI-IINE.

Specification of Letters Patent No. 24,704, dated July 5, 1859.

To all whom it may concern:

Be it known that 1, JOHN I. HOLLOW, of Fredericksburg, in Spottsylvania county and State of Virgina, have invented certain new and useful Improvements in Combined Threshing and Cleaning Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, through letters of reference marked thereon, forming part of this specification, in which Figure 1, represents a top view or plan of my entire machine. Fig. 2, a side elevation. Fig. 3, a reverse side elevation, and Fig. 4, a vertical longitudinal section taken on the line 00 m of Fig. 1.

The same letters of reference occurring on the several figures indicate the same parts of the machine.

My invention has reference to that class of machines in which the thresher and cleaner are combined, all of which heretofore constructed, are too complicated, cumbersome, laborious to operate, liable to get out of repair, and expensive, to meet the wants of the agriculturist; to furnish a machine that is as nearly as possible free from all these objections is the object of my present invention.

To enable others to make and use my invention I will describe its construction and operation.

The threshing machine (A) is constructed in any of the well known forms now in use consisting of a toothed concave (B) and toothed cylinder (C) which latter is made to revolve in suitable framing (D) inclosed with boards or panels to direct the passage of the straw, chaff and grain, and having an opening (E) for the ingress of the unthreshed grain, and an egress opening (F) whence it is delivered onto the carrier and cleaner (G) after passing the thresher.

The carrier (H) is a slatted bottomed chute with a series of notched ribs (R) arranged longitudinally over the slatted bottom, which ribs are notched to such an angle that the longitudinal portion of the surface is horizontal so as to offer no resistance to the progressive motion of the straw, while the vertical portions tend to carry it forward by the reciprocating motion. This carrier is slightly inclined from the thresher I downward, and has a longitudinal motion,

which with the notched ribs carries the straw forward and discharges it over the lower end; while the straw is thus conveyed away, the grain is shaken through between the slats on to a chute (I) which is inclined in the opposite direction to that of the slatted bottom of the carrier and is delivcred onto a coarse screen (J) made of perforated wood, which is attached to the sides of the chamber in such manner that it presents a curved or dished surface sufficiently so to insure the grain being shaken through the perforations instead of over either end; on passing through which, it falls on a wire screen (K) the meshes of which are of just sufiicient size to allow the grain to pass through, after which it is conducted by the shoe (L) into a sack or receiver. This carrier, chute, and screen combined is suspended by links (M) at each end in a frame (N) so as to admit of its vibrating endwise to facilitate the passage of the straw and grain to their respective egresses.

To the frame (N) is attached a revolving fan (0) so arranged and incased that the blast caused by its revolution is injected into the screen chamber (P) in such direction that it is divided above and below the upper screen (J) and blows out the chaff and broken straw that may have passed the carrier, and discharges it through an outlet (Q), while the straw is passing in a direct line over the slatted carrier and discharging at the end, and the grain is being shaken through the screen (K) and discharge by the shoe (L).

The toothed cylinder (C) of the threshing machine is rotated by a belt (S) from the horse power or steam engine by passing around the pulley (T) on its axis. This belt is diverged from a straight line by the band wheel on the periphery of which it rests, and by which, when the belt is in motion, said band wheel is rotated; on the axis of this band wheel is an eccentric (o) by the revolutions of which reciprocating motion is communicated through the connecting rod (w) to the carrier (H), to which it is attached at (an); the eccentric giving a smooth and easy motion, free from the slightest jerk which is so destructive to all machinery; on the other end of the axis of the toothed cylinder (C) is a pulley (Y) from which by a band (Z) around the pulley (a) rotary motion is communicated to the fan When it is desirable to move the machine to another location the carrier, fan and screen may be detached from the thresher by unscrewing the wing nuts (7)) when both may be transported with facility and safety. I

From the above it will be seen that the arrangement and construction of this machine is brought to the greatest degree of simplicity there being but one belt, besides the main driving belt, to operate all the parts, While all other machines to accomplish the same end have to elevate the grain from one position to another through the various operations, consequently requiring many additional mechanical devices, increasing the cost of the machine and rendering it more cumbersome, laborious to operate and more liable to get out of repair.

Having thus described my invention What I claim as new desire to secure by Letters Patent is JOHN I. ROLLOW.
